Grounded Patch 0.4: Koi Pond Now Available

Reading Time: 6 minutes

Grounded, the back-yard survival game that puts players into a “Honey, I Shrunk The Kids” sized world for players to explore, craft, gather, and survive in, still in its Early Access phase, released there 0.4 game patch today. The 0.4 update represents the fourth major update to the game, aside from the numerous smaller bug fixes and patches that have come along since we got our first look way back in July.

The fourth major Grounded patch features some new and exciting features that players have been asking for out of the ground-breaking multiplayer game. Obsidian’s Social Media Manager Shyla Schofield released the Grounded Developer Vlog 8 today, which coincided with the game’s featuring in the Xbox Series X launch today as part of the Xbox Series X Launch Celebration, which featured a big segment on Grounded, including an interview/discussion from Ben Brennecke, as well as demos of the updated gameplay. Shayla talks about the big update coming in 0.4 – the introduction of the Koi Pond.

Though the Grounded pond has been an ever-present fixture in the backyard, the pond has, until this patch, essentially served as more of a death-trap as well as a source of curiosity and debate on future updates more than anything else. The Koi Pond introduces a whole new underwater map to explore, with new resources to be gathered as well as new recipes/plans for gear that can be built to help with underwater exploration. It also comes with new hazards unique to the underwater world, including the introduction of apex-predator Koi fish that try to eat you, friendly tadpoles that players can use to help swim around and as we might have expected from the sadists at Obsidian – underwater swimming spiders known as “Diving Bell Spiders,” which are, terrifyingly, a real thing. In addition to new creatures to help and hurt players, players will have access to new hidden features underwater, as well as the addition of new home base build options.

Not all of the additions are underwater-based. Newly added with this update is also “The Bird”, which will drop feathers occasionally, which can be used, among other things, in the production of more accurate arrows.

Grounded’s Dev team also made an announcement with this patch, that they will be changing their update approach, with plans to release fewer big updates, like the one today, rather than numerous smaller incremental updates that have featured more recently, and that this move is a direct result of community feedback. Some of this may be tied to some stability and quality issues that some recent updates had caused, including a recent announcement update that came out for Grounded that had players losing saved games and running into other challenges. Though Grounded is still essentially in an extended Beta test with gameplay occurring during ongoing development, hiccups like this are expected to happen, it can none-the-less be frustrating for players to lose hours of hard work as they help the dev team test out and develop the games features.

Here is the full letter from the developers that came out today with the 0.4 update announcing some changes to the update structure, as well as future plans for game development:
